Uninstall java-addon alone

Hi all...
I have installing XI.
I have followed XISR1 Installation guide and completed installation till java-addon. Now i experience some problem with Java stack. So i want to uninstall only java-addon. Is there a way that i can uninstall only java-addon.

hi Pran,
there is one risky way. Find your java instance and remove the corresponding entires from Services registry (SAP<SID>_<INSTANCE NR>) and restart the system. this might remove the references to the java stack in your server. so, in the perspective of OS, your Java stack is gone.
you may take a backup of the registry contents you are going to delete. just in case something goes wrong, import the registry contents into your regedit and restart the system. the system should rollback to its original state.
if your so-called uninstallation is successful, reinstall Java addon again. (this might not let you create the same instance but in the end your server will have only one java instance).
again, i seriously tell you this is very risky. if you have time and can do R & D, you may go ahead and try this at your own risk. otherwise, remove all and restart your installation.
Regards

We need to reinstall the JAVA part alone in ABAP+JAVA

Dear Sir/Madam,
We have an SAP ECC 6.0 system with ABAP+JAVA components. Now there are some issue with our Java comp. and I'm unable to start the JAVA engine. As we have done little configuration on JAVA side we are planning to reinstall the JAVA part alone.
1)Can we uninstall the the JAVA Component alone from the ABAP+JAVA Central instance?(Without affecting the ABAP Part)
2)Can we install a new JAVA addin in our existing ABAP+JAVA system?
3)If yes; is there any special steps appart from the master guide "4.4.2 Installing the Java Add-In for an Existing ABAP System" ?
Thank you,
Siju

Thank you for the update,
We have done a Homogeneous system copy from our DEV system to QA system(SAP ECC 6.0 ABAP+JAVA with Oracle 10g)
Our issue is we are unable to connect the VA it shows "Unable to lookup connection default".
We've noticed that the Instance ID in our config tool still shows the DEV Instance ID and the Instance.properties files shows the QA system instance ID.
In our DEV it's given
com.sap.engine.bootstrap.Bootstrap
./bootstrap
ID0035522
and QA it's
ID0031354
In have changed the SID,HOST NAME and Instance ID in the config tool to the QA system param. as per the suggestions in the below link
Re: J2EE info status unavailable after system refresh
but still I am unable to connect the VA.
the log JVM_bootstrap.out is given below

WAS 6.40 SR1 - abap client copy after java addon install

After installing the WAS 6.40 SR1 abap+java central instance and database instance... we inadvertently proceeded to install the java add-on (j2ee). We realized we needed to do an abap client copy of "000" to a new client.
Is there a way to do the client copy, then point the java engine at the new client?
If not... what are our options. Is there a way to just uninstall the existing java-addon, do the client copy, then re-install the java-addon? We're hoping that this is correctable and we don't need to do a full re-install.
Thanks in Advance for any assistance.

Hello,
can anybody help me?

Uninstalled Java 6, installed Java 7, keep getting requests to install Java SE 6 plugin. Why?

Because of the security issues with Java, I uninstalled Java 6 (using various terminal commands) and installed Java 7 from Oracle's website. Looking at /Library/Internet Plug-Ins, I can see that JavaAppletPlugin.plugin is there, and Get Info tells me that it is part of Java 7 Update 09.
However, when I use Safari to try out a Java test page, or use one of the Java-based programs that I need to run for work, I get a message that says, "To open “PluginProcess,” you need a Java SE 6 runtime. Would you like to install one now?" (PluginProcess is replaced by the program name if I am running a Java program.) If I click "Install", the Apple version of Java 6 gets installed.
This doesn't make sense to me. Why would Java 7 need the Apple Java 6 environment? And why doesn't Safari or other Java based programs recognize that the Java 7 JavaAppletPlugin.plugin is on my computer already?
Although I'm not really an IT person, I am pretty handy with the Terminal and command line operations, so if fixing this means using the command line, I'm good with that.
Thanks!

I think I've found a solution to the problem that Java Applications doesn't use Java 7. This seems to work for me. Try it and please confirm if it works for you.
1.
Install Java SE Development Kit 7u9 from Oracle
http://www.oracle.com/technetwork/java/javase/downloads/jdk7u9-downloads-1859576 .html
2.
Execute something that triggers the prompt to install Java SE 6. for example i web site using java applet. And follow through with the installation. (after this you will have three java versions: Java6 32-bit, Java6 64-bit, Java7 64-bit)
3.
Open a new terminal window and execute the following commands.
$ cd /System/Library/Frameworks/JavaVM.framework/Versions
$ sudo rm CurrentJDK
Password: ********
$ sudo ln -s /Library/Java/JavaVirtualMachines/jdk1.7.0_09.jdk/Contents/ CurrentJDK
$ sudo ln -s CurrentJDK 1.7
$ sudo ln -s CurrentJDK 1.7.0
Note: I don't know if the last two lines are necessary, but I just tried to follow the existing pattern.

Firefox is blocking Java even though I had the updated version. Now I can't update or uninstall Java.

On 4/2/12 Firefox informed me that Java had serious issues with security and I should let them block it, so I did. Later I found I couldn't play Pogo anymore so I tried to enable Java but it still wouldn't work. My Java is up to date, 6.0.290.11. Now I cannot update Java, error 1606, nor can I uninstall Java from my computer, same error cannot access location, in order to re-install. Since I was using the most updated version, my Java should not have been blocked. Anyone else have this problem? I am stuck and can't update or re-install or anything.

I have the latest version and today it blocked it

How do i uninstall java from my MacBook Pro running Lion?

I would like to uninstall Java from my Lion OS running MacBook Pro. *it got installed a while back while running a Java program, and due to Fashback and other holes, I would like it off of my system, other than a complete re-install, how do I remove it?
Thanks in advance.

Uninstalling Java on Lion
There's a lot more installed than what that article says. The Java installation package includes much more than just:
/System/Library/Java/JavaVirtualMachines/
Take a look at the package with Pacifist.

I have uninstalled Java - how do I get it back?

Hi,
I uninstalled Java & Adobe FLash - just as a precaution - did a scan and check and clean up of my Mac, now how do I get those two applications back? And ensure they are clean?
Thanks
Tracy

I have reinstalled Java - worked fine - thank you. I was reading the other posts about the previous version being better. SHould I uninstall again and reinstall the earlier version Javafor Mac OS 10.7?
Stick with the latest version. In that particular case he needed the previous version because a program he uses didn't work anymore with the update.
Also when I went to the adobe link it was all in Italian. Is there an English version or doesn't it matter?
I think the Flash Player is multilingual. Anyway if you want to be sure go to the following page and then click "Get the latest version"

SAP JAVA Export alone NW7.3

Hi All,
We are using NW7.3 for SAP BPM Application.
We are planning for Source system java export alone in NW 7.3. But we don't find the option for central instance export under based on AS java in SAPINST. only database instance export option only exist. I know there is no central instance concept from NW7.3. We are trying to refresh the CATE system using Production system. we are already performed database refresh in CATE system and trying to export java profile in source system and import into CATE system.
Please tell us the procedure for central instance export in NW7.3.

Hi,
there is no option to export CI in NW 7.3. SAP has moved all java related data to Database.

Deploying Java stand alone application in Weblogic server

Hi All,
We have an java stand alone application which our client uses. Suddenly they came up with a requirement of using this application from web logic server.We have following directory structure for our application
myapp
- config -> contains all configuration files
- logs -> contains log files
- ssl -> ssl related files
- samples ->contians stub's
- myapp.jar
How to deploy our standalone application in to weblogic server?.
We tried putting whole myapp folder in WEB-INF folder , and from the servlet we are able to invoke an method in an class file( in myapp.jar say Test.getInstance()) but it couldnt find configuration files (in config folder ) and it is throwing an error. We have a class called Test in myapp.jar and when we call getInstance of the class it loads all config files - config file location is hardcoded as /config/myconfig.xml , and we are facing problem here because it couldnt find myconfig.xml.
We also tried packaging whole myapp folder in to jar , but with that also we faced the same problem
Please let us know are we proceeding in the right way and how to deploy our application in weblogic server.We dont prefer making changes to our code at this point of time.
Any info on this will be very helpful to us.
Regards,
Suresh

Hi René van Wijk,
Thanks for quick reply. Link you mentioned gave a basic idea of application structure , but still i couldnt get deployment process.
Am very much new to weblogic.Can you please let me know how to deploy our standalone application in to weblogic, with out making any changes to the code.
Below is folder structure of my java stand alone application *( not webapplication)*
myapp
- config -> contains all configuration files , for ex:- myconfig.xml
- logs -> contains log files
- ssl -> ssl related files
- samples ->contians stub's
- myapp.jar
We have logic to load configuration file (config/myconfig.xml) , in an class and we are not allowed to make any changes to this code, so we cant use Thread.currentThread().getContextClassLoader().getResource(...) .
Regards,
Suresh

Error when uninstalling java

I get the following message when I try to unistall 1.4 of java:
error number 0x80040702 description failed to load dll:actpanel and the uninstall fails. Any help on this would be appreciated.

This is where the nerd of me comes out.
- This is NOT a Java Problem -
This is actually an installshield problem and nothing much has really been documented on this.
This error occurs when Java's setup program doesn't kill itself correctly, either installing or uninstalling itself.
I 'believe' (Untested but I believe strongly) that removing from a windows box registry the key
HKey_Local_Machine//Software//Microsoft//Windows//Current Version//Uninstall//{IDontHave-WindowsSoICant-Check-WhatThisShould-Be}
-= The Java Uninstall Thing Key =- (I am unsure what this is because I dont have windows - not that I hate windows or anything, just dont own a copy)
Reboot, and uninstall again, it should uninstall just dandy. But keep in mind, its probably just easier to type "format c: /u", or uninstall java 1.4.x maunally.
David Grocke
P.S. If you ever get the 0x80040702 error it can 'most probably' be fixed by this. It could also be a required dll is corrupt or missing, or is locked by another program that installshield needs (such as installshield itself).

How to uninstall Java (JRE MSI) while keeping Internet Explorer open?

I have a situation where I need to have the ability to uninstall Java (currently JRE 1.7 Update 75, but could really be any version in the future). We are using the JRE MSI. I know how to uninstall it silently just fine, but the gotcha problem comes in that we have thousands of computers and some of them may have IE running during the uninstall.
Now normally I would just use taskkill.exe to terminate IE ahead of time then run Java uninstall. However, we are being told for the uninstall, this isn't an option even if we notify the customers about IE closing. So I'm looking for a command line way to uninstall Java, but allow it to be successfully uninstalled if IE is running (If a reboot is required after the fact, that is fine).
I have tried several things without success already:
MSIRESTARTMANAGERCONTROL=Enable (And Disable)
IEOPEN=1
IERESTART=1
In every case, I keep getting a Java Window that reads the below:
If I choose Later, then it will continue upon the next restart of the computer, which would be fine, except there doesn't seem to be a way to choose this option using the command line or a property??
I would be even be happy to trick Java into thinking it isn't being used currently even if the browser is open, but I can't seem to figure out how Java knows it is being used or not currently used.
(FYI, if you install Java while IE is running that is fine, and if you don't close IE after the fact then run the uninstall command right after, it uninstalls fine even though IE is running. I believe that is the case because the plug-in didn't fully get activated in IE until a close and reopen).
Any ideas on how this can be accomplished? Thanks.

How to uninstall Java runtime 1.5 completely and then install Java 1.4...

Dear Friends,
I have a software running with Java runtime 1.4. When the new version of Java (1.5) became available, I installed it. And then the software I am using becomes useless since it doesn't work with the new Java 1.5. I uninstalled java 1.5 and then reinstalled Java 1.4. But it doesn't work. I'll be very glad if someone can help me uninstalling Java 1.5 completely from my computer.

I have a similar problem under Windows XP. When I go to "Control Panel" and try to remove that Java installation, clicking on the "Change/Remove" button has no effect whatsoever: the program name simply dims for a moment, and then reappears with no evident change. Is there not a separate routine available to effect a removal, so the program may be reinstalled?

Uninstall Java?

After installing the latest version of iTunes 7, playing Java games on Pogo is painfully slow and most of the time Java freezes up. I need to uninstall Java and then reinstall it but I don't know how to, can anyone help me please?
System Info - Mac OS X Version 10.4.8

Everybody gets these java permissions in DiskUtility. I do not feel this is a concern as long as you are running the most up to date version
Apple Computer supplies their own version of Java. Use the Software Update feature (available on the Apple menu) to check that you have the most up-to-date version of Java for your Mac.
Hope this helps
